During Production Inspection Service in China

What is During Production Inspection (DPI or DUPRO Inspection)?

During Production Inspection (DPI), also known as DUPRO Inspection, is an essential on-site evaluation performed when 20-50% of your production is completed and packed for shipping. This in-process inspection aims to identify any deviations or product issues early in the manufacturing cycle, providing a critical quality check for your finished products.

The DUPRO inspection ensures that all manufacturing processes and products adhere to the agreed standards and timelines. It also serves as a follow-up to address any quality issues identified during the Pre-Production Inspection.

Our experienced quality engineers offer tailored recommendations for corrective actions, helping to maintain smooth production operations. You will receive a comprehensive inspection report via email within 24 hours, detailing all findings and recommendations.

What Does the During Production Inspection Report Include?

A During Production Inspection (DPI) report provides a comprehensive overview of various key aspects of the manufacturing process. Here’s what you can expect to find in the report:

1. Verification of Production and Quality Plan: Assessment of the production and quality management strategies to ensure compliance with established standards.

2. Storage Condition Inspection: Evaluation of storage facilities to confirm that conditions meet necessary requirements for product integrity.

3. Packaging and Labeling Inspection: Review of packaging methods and labeling accuracy to ensure they align with regulatory and client specifications.

4. Barcode Verification: Confirmation that barcodes are correctly implemented for tracking and inventory management.

5. Inspection of Semi-Finished Products: Examination of semi-finished products at key stages in the manufacturing process to ensure quality consistency.

6. Workmanship Appearance Inspection: Random inspections based on Acceptable Quality Level (AQL) standards to assess the overall appearance and craftsmanship of the products.

7. Functionality, Size, and Measurement Checks: Verification that products meet specified dimensions and functionality requirements.

8. Reliability and Safety Testing: Conducting tests to ensure that products are safe and reliable for consumer use.

9. Additional Client-Specified Requirements: Addressing any unique inspection criteria or requirements outlined by the client.

Sampling techniques used in the DPI report adhere to internationally recognized AQL sampling procedures, such as ANSI/ASQC Z1.4-2003 (ISO 2859-1), or any other specific sampling methods requested by you.
